Switch to the atomic scale setting, if you are using the Coulomb's law simulator. You have two charges, one of size -2e, and one of size 8e. They are separated by a distance of 31 pm. Calculate the electric force between the two. Report your answer in microNewtons (N). Be sure to include sign in your answer, where positive means a repulsive force and negative means attractive. Remember, e = 1.6 x 10-19 Cand 1pm 10-m
